Distinguish between gaseous exchange and respiration

Answers

Answer:

Respiration is the process in which food is oxidized to release energy. Complex organic compounds are converted into simpler ones, e.g glucose into CO2 water and energy released. Gaseous exchange is the diffusion of gases from a region of higher concentration to a region of lower one.

Explanation:

Breathing is the physical process by which air is passed on a gaseous exchange surface i.e. ventilation of the gaseous exchange surface. It involves Inhalation and Exhalation.

Gas/Gaseous exchange is the process whereby gasses diffuse across a gaseous exchange surface. In humans, oxygen diffuses from the inhaled air into the blood and carbon dioxide diffuses from the blood into the exhaled air. The gaseous exchange surface here being the Alveoli.

Respiration is the metabolic process whereby organic molecules are broken down to release energy in the cells. In humans, this process takes place inside the mitochondria of cells. Aerobic respiration requires oxygen whereas qnqerobic respiration takes place in absence of oxygen.

C. Discovered a basic principle of chemistry, that all matter is composed of atoms.
D. Discovered a basic principle of biology, that all plants and animals are made of cells.

Answers

The answer might be D

Matthias Schleiden and Theodor Schwann made a significant contribution to science as they discovered a basic principle of biology, that all plants and animals are made of cells. So the correct option is option D.

Matthias Schleiden and Theodor Schwann made the contribution of discovering a fundamental principle in biology known as the cell theory. In the 1830s, they independently proposed that all plants and animals are composed of cells. Their work laid the foundation for our understanding of the structural and functional units of life. Together, the contributions of Schleiden and Schwann formed the basis of the cell theory, The correct option is option D.

What form is DNA in during mitosis?
A. protein
B. ribosome
C. chromatin
D. chromosomes

Answers

Answer:

Chromosomes form is DNA in during mitosis.

Explanation:

In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes.

During mitosis, DNA is in the form of chromosomes, which is option D, as the chromosomes are condensed and highly coiled structures made up of DNA and associated proteins called histones.

During mitosis, a cell divides into two daughter cells that are genetically identical to the parent cell. Chromosomes are critical to this process because they carry the genetic information necessary for the formation of the new cells, and before mitosis begins, the chromatin (a complex of DNA and proteins) in the nucleus of the cell condenses into visible chromosomes. This condensation process involves the compaction of chromatin into a more compact and organized structure.

Answers

Answer:

Célula procariota y procariotas.

Explicación:

La célula procariota es un tipo de célula que apareció por primera vez en la Tierra hace unos mil millones de años. Estos tipos de células están presentes en los procariotas, lo que significa que estos organismos no tienen un núcleo verdadero o una membrana nuclear alrededor del núcleo y otros orgánulos de la célula. El ADN del organismo procariótico se encuentra en una parte central de la célula que se conoce como nucleoide. La pared celular de un procariota actúa como una capa adicional de protección, ayuda a mantener la forma y estructura celular y previene la deshidratación.

what effect will an invasive species have on the carrying capacity of an ecosystem?
a) the carrying capacity will increase for those in competition
b) the carrying capacity for all animals will stay the same
c) the carrying capacity for everyone will decrease and then increase rapidly
d) the carrying capacity will decrease for those in competition for same resource

Answers

the answer to this question should be D) the carrying capacity will decrease for those in competition for the same resource.
An invasive species will consume food resources that the native species require. As a result, the maximum population that can be sustained will be lessened, since there is new competition and less food.

The effect an invasive species will have on the carrying capacity of an ecosystem is the carrying capacity will decrease for those in competition for same resource.

What is invasive species?

An invasive species refers to an organisms such as amphibians,plant, insect, fish, fungus, bacteria that is not native to an ecosystem but it is introduced into the ecosystem and causes harm to the native species. They can harm the environment and also humans.

Therefore, The effect an invasive species will have on the carrying capacity of an ecosystem is the carrying capacity will decrease for those in competition for same resource.

Cuáles son las condiciones ambientales, factores abióticos, que pueden presentar variaciones en los diferentes ambientes?

Answers

Respuesta y explicación:

Los factores abióticos son aquellos componentes no vivos que determinan las condiciones ambientales en las que los seres vivos (factores bióticos) van a vivir.

Estos factores abióticos pueden ser el pH, la temperatura, los niveles de oxígeno y otros gases, y la humedad, entre otros. Todas estas variables pueden presentar variaciones que van a determinar si es viable o no para diferentes especies el subsistir en esa área.

Cada ser vivo se desarrolla en regiones geográficas definidas y sobrevive ahí mismo gracias a rangos de tolerancia que poseen para resistir pequeños cambios en los factores ambientales. Cuando los cambios sean muy pronunciados, es entonces que la vida para ciertas especies se verá amenazada y por eso deberán encontrar otro lugar donde vivir.
